No one has answered because either they don't know or the ones that do haven't read it yet.

I'm sure it's possible but I haven't seen it anywhere and since I don't need or use such a thing I haven't really looked into it. You might dig around the \include\tools\gpOutput.php to see what is going on. . .I don't know enough php to figure it out. . . and just don't need it as I don't want the page title called anywhere ;)

I'm sure there is something in the code especially where the menus are created, but you will need to go hunting.
